CUTION The external air intake opening should be positioned away from the exhaust openings of combustion gases. The intake of such gases could cause a lack of oxygen in the room. The external air intake opening should not be positioned where discharged air may directly enter it. situation like this will lead to the room being contaminated and this may pose a health risk. Netting or something similar should be provided at the external air intake opening to prevent birds or other things interfering with the unit. Nests or other foreign objects should be removed. That could cause a lack of oxygen in the room. To pierce the metal duct through the metal lath or the wire lath or the metal plate of the wooden facility, do not forget to insulate electrically between the duct and the wall. Otherwise, it would cause an electric shock or an electric leakage. Install the outdoor duct in a falling gradient toward the outside so as to prevent water from coming in. If it is not installed so, the building is likely to be flooded, wetting the household effects. Heat-insulate the outdoor duct (including the indoor side, if necessary) to prevent dewing. If heat insulation is not adequate, water likely goes indoor and wets the household properties. When it is high humid and high temperature inside the ceiling, a ventilation system must be installed inside the ceiling. Otherwise, it could cause a fire or an electric leakage. Install the power line and the connecting line with accuracy so the power source cover may not float. If the installation of the electrical control cover is inappropriate, the pin connection area is likely to cause a heat generation, a fire and an electric shock due to dust or powder.
